SPECIFICAION 'forming part of Letters Patent No. 293,706, dated February 19, 1884. I Application filed July 25, 1883. (Noinodel.)

To @ZZ whom it may concern: Upon these rollers D are secured on each a Be it known that I, ADDISON BRADFORD, of pair of cams oreccentrics, a a, which operate o Brooklyn, in the county of Kings and State of a pair of side levers oryokes, b b, which have NewYork, have invented certain new and useon their upper end an inwardly-projecting 5 ful Improvements in Iiubricators; and I do bearing, c c, vthat works on the face ofthe echereby declare that the following is aful1,clear, centrics in such manner that an up-and-down and exact description of the invention, which movement is imparted to them when the oilwill enable others skilled in the art to which `it rollers revolve. These yokes work up and appertains to make and use the same, reference .down in guideslides d d, which are secured to v Io being had to the accompanying drawings, and the cross-head O. -The lower ends ofthe yokes to the letters of reference marked thereon, are secured togetherV by tie-rods 'or small which form vpart of this specification. shafts e e, which carry small wheels or rollers 6o This invention relates to lubricators for carf. These small rollers are adapted to be subaxle' journals andthe like, and has for its obmerged in the lubricating-oil, and when the 15 ject the economical supplying of lubricant to e'ccentrics rise up they carry these small rollthe axle, by means of rollers or equivalent' ers f with them, Abringing them in Contact means,in suitablequantities,without,`however, with the large rollers, to which they impart having the rollers themselves in contaot with the oil adhering to them.

These journaled wheels or 8 5 A is the frame, which may be made of any rollers, with cams onl their sides, are for the suitable form and material.

Across the base-frame A, I construct what I l When the longer side of the cam goes up, it term a cross-head or 1"ran1e,77 C, having raises the drop, bringing the small roller in 45 two sides, and carrying a pair of rollers or oilthe lower end of the drop in connection with ers, D, mounted therein in suitable bearings, the rollers ofthe lubricator that bearagainst and adapted to revolve bythe motion impartthe axle -`journal, supplying at each time a ed to them by the rotary action of the journal. small quantity of oil, that is taken off by the revolving luln'icatorrollcrs, and is thus applied to the axle-journal. By causing a greater or less contact-point to the feeders the quantity of oil supplied is regulated. The contactpoint of the feed may be of yielding substances, if desired; also, the contact part of the roller may be of any yielding substance.

A suitable frame-work, to rest on the bottom of the journal-box, has attached to it springs fastened at one end, the other end rising, so as toconnect with the frame-work in which the rollers are `iournaled to hold them, the said rollers bearing contact with the axlejournal. The springs thus adjust the rollers to the condition of the box and journal. To this framework, resting on the bottom of thej ournal-box, are also attached springs and eontaet-bear ing ends to take off the surplus oil at the rear ofthe bearings.

At Fig. 3 will be seen a wire connected to the frame-work, which may be loosely bent around asmall rod, one end operating against the cam of the roller. The other, by gravity or tension, goes down into the oil and up against the other roller as actuated bythe cam movement ofthe cam-roller. Fig. et shows the feedwire bent so as to feed the oil to the roller that gives it itsaction; also, that one wheel or roller may be used, instead of a greater number, to do the lubricating, and that instead of a cam there may be a projecting pin on lthe side of the wheel. Said pin may have a loose roller on it to reduce friction, or the wheel might be groovcd to operate the feeder.

The roller or wheels, with their frame-work and bearings, as represented in Figs. l and 2, may be applied to the frame with raised springs, as represented in Fig. et. It is evident that said roller or rollers may operate the feeders, so as to apply the oil direct to the journal.

Having described simple forms of my lubricator, it is readily seen that there may be modifications of construction within wide scope of my inv ention, therefore I do not restrict my self to the forms described.

Vhat I claim as new, and desire to secure by Letters Patent, is

1. Alubricatorhavingthebase-frameadapted to rest on the bottom of the journal-box, and having springs secured thereto, which are adapted to sustain a lubricating device, which device is kept in contact by the resiliency of said springs, substantially as described.

2. The combination, in a lubricator, of the frame A, the su pporting-sp rin gs, and the lubri eating-rollers, mounted as shown, and operating as described.

3. The combination, in a lubricator, of the frame, the springs, and cross-head carrying the oil-supply rollers, with the cams and sliding yokes or their equivalents, and oiling dcvice, operating as set forth.

4. The combination of the frame, the supportingl springs, and oil-supplying devices with the wipers for wiping oft' the surplus oil, substantially as described.

5. `A lubrieator having the base-frame, the supp0rting-springs, the frame carrying the rollers, said rollers having eecentrics or cams or their equivalents for operating oil-supply devices, for the purpose set forth. r

-6. A lubricator having one or more rollers adapted to be operated by a journal, said roller or rollers being provided with eccentries, cams, or their equivalents for operating oil-supply devices.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

ADDISOBT BRADFORD.
